CIGS solar cell is considered to be another strong candidate for a dosimeter to measure radiation level in the damaged reactors at Fukushima Daiichi Nuclear Power Plant in addition to InGaP solar cell. Degradation characteristics of a CIGS solar cell against alfa-ray, which is one of the major radiation particles in the reactors, were obtained by 1 and 5-MeV helium-ion irradiation. The degradation was compared with electron and proton degradations and analyzed using the displacement damage dose method.}, publisher = {IEEE}, title = {Displacement Damage Dose Analysis on Alfa-ray Degradation of Output of a CIGS Solar Cell}, year = {2021} }
